This experiment principally attempted to map the movements of lateralized auditory images associated with 1‐pps unfiltered clicks heard at two intensity levels and over a wide range of interaural time and intensity differences. With sensation level at 16 db in both ears, lateralization effects were heard for interaural time differences as large as ±15 msec. With 16 db SL in one ear, the minimum level in the other ear producing effects was −6 db, the effect usually being a “bulge” of the image in the audible ear occurring within ±2 msec interaural time difference. Approximately the same time‐difference limits were found, respectively, for 36 db in both ears and 36 db in one ear paired with the minimally effectual −2 db in the other ear. The time‐difference limits within which fusion was “complete” (only one image heard) ranged from 3–7 msec, louder ear leading, to 3 msec, louder ear lagging. It is suggested that the results set a bound on the contribution of direct binaural correlation to the precedence‐effect phenomenon.
